stepper motor music

Hello all,

How would you go about making a project like this one? Stepper Motor Music With an Arduino - YouTube
I want to use stepper motors to make music, and I want to wire the whole circuit into a hoodie using a lilypad.

You are going to have trouble mounting all that hardware in a hoodie. You will also have to attach some kind of resonator boxes or plates to the steppers to get any reasonable amount of volume, especially if you use steppers small enough to mount on clothing.

Could you, perhaps, substitute speakers and blinking lights for the turning flags?
